Bills activate TE Shawn Nelson

ORCHARD PARK, N.Y. -- The Buffalo Bills have activated tight end Shawn Nelson and cut linebacker Chris Ellis, a former third-round pick who became the winless team's latest castoff.

The Bills (0-5) had until Monday to activate or release Nelson, who opened the season serving a four-game suspension for violating the NFL's substance abuse policy.

Ellis was the odd man out after failing to make the transition from defensive end to linebacker in the Bills' new 3-4 defense. The third-year player started the first two games this season, but was inactive in two of the past three.

It's the latest move by a team in upheaval, coming a week after Marshawn Lynch was traded to Seattle, and two weeks after former starting quarterback Trent Edwards was cut.
